controlling the X11 desktop using smartphone, instead of keyboard and mouse
So this is what I succeeded in doing:
I downloaded the portable archive of UnifiedRemote from here:
(Perhaps it would have been possible to download a different release, I was not able to install the raspberry pi deb file from there, so I opted for the portable version instead).
tar -xvzf urserver-220.127.116.118.tar.gz
Of course, installed the UnifiedRemote android app. There's other client apps, that's what I've been using.
Then, cd to the folder where the UnifiedRemote was extracted and run it...
And that's it, the server is running and the mobile device can control mouse and keyboard movements and presses on the desktop. Works great!
The only issue I've been having, perhaps someone can assist, I was unable to include the urserver in the boot sequence, to load automatically whenever the desktop is loaded, and to stop when it is logged out of. Any suggestions?
